There has long been debate over the exact location of the geographical centre of the United Kingdom, and its constituent countries, due to the complexity and method of the calculation, such as whether to include offshore islands, and the fact that erosion will cause the position to change over time. There are two main methods of calculating this "centre": either as the centroid of the two-dimensional shape made by the country (projected to the Airy ellipsoid then flattened using the Transverse Mercator projection), or as the point farthest from the boundary of the country (either the sea, or, in the case of constituent countries, a land border). These two methods give quite different answers.
Traditional locations
The town of Haltwhistle in Northumberland has banners stating that it is the "Centre of Britain".{{Cite web |url=https://www.bbc.co.uk/news/uk-28841108 |title=Scottish independence: The town at the centre of Britain |author=Vanessa Barford |publisher=BBC News |date=22 August 2014 |access-date=20 November 2015}} By another calculation the centre can also be said to be Dunsop Bridge, Lancashire, 71 miles (114 km) to the south.
However, in 2002 the Ordnance Survey conducted studies that pinpointed the respective centres more precisely, and it is their results that are quoted below.{{cite web|first1=Gemma|last1=Social Media Manager|title=Where is the centre of Great Britain?|url=https://www.ordnancesurvey.co.uk/blog/2014/08/where-is-the-centre-of-great-britain-2/|website=The Official OS Blog|publisher=OS|date =22 August 2014|access-date=20 May 2017}}

}}The centroid is a mathematically derived point that is in every sense the centre of a two dimensional area like a piece of land. If a straight line is drawn through a centroid in any direction there will be equal length of the line on either side of the centroid as measured from it to the boundary if the line is unbroken on either side. If a line crosses an inlet of the sea then it can be considered as a stick of uniform weight with a material of negligible weight crossing the water, the line would then balance precisely at the centroid point if suspended.{{Location map+|United Kingdom Lancashire

Put simply, the centroid is the point at which a cardboard cut-out of the area could be perfectly balanced on the tip of a pencil. Islands are assumed fixed to the mainland in their precise position by invisible rigid weightless wires. A mathematical method is used to do the balancing to a much greater accuracy than the practical method could achieve.
Unless stated, positions are the centroids of the two-dimensional shapes made by the countries. Calculations include offshore islands unless stated.

Centre of population
- This calculation depends on the method used (mean, median or geometric median; see Centre of population for details).
::A calculation by Danny Dorling using the mean (least squares) method based on local authority district data from the 1990s gave the population centre of Great Britain at Appleby Parva, Leicestershire, 20 miles south of Derby. Since then, the population centre will have moved slightly south and east.{{cite web |url=http://reporter.leeds.ac.uk/477/news.htm |title=News Item: |access-date=25 November 2007 |work=University of Leeds |archive-url=https://web.archive.org/web/20061003073229/http://reporter.leeds.ac.uk/477/news.htm |archive-date=3 October 2006 |url-status=dead }}{{cite web |url=http://www.applebymagna.org.uk/population_centre.htm |title=Population Centre |access-date=25 November 2007 |work=Appleby Magna & Appleby Parva | archive-url = https://web.archive.org/web/20071123015253/http://www.applebymagna.org.uk/population_centre.htm| archive-date = 23 November 2007}}{{cite book |last1=Dorling |first1=D |last2=Atkins |first2=D J |date=1995 |title=Population density, change and concentration in Great Britain 1971, 1981 and 1991 (Studies on Medical and Population Subjects No. 58) |url=http://www.dannydorling.org/?page_id=1449 |publisher=HMSO}}
Centre of England

File:The Centre of England - geograph.org.uk - 372568.jpg]]
For centuries the parish of Meriden to the west of Coventry has claimed to be the geographical centre of England, and there has been a stone cross there commemorating the claim for at least 500 years. The justification is that the point farthest from the sea is in the parish.{{citation needed|date=November 2014}} Morton, Derbyshire also claims to be the centre of England as it is not only midway along England's longest north-south axis,{{citation needed|date=November 2014}} but also midway between the east coast and the Welsh border.{{citation needed|date=November 2014}} Claims are also made for a tree, the Midland Oak, in Leamington Spa, Warwickshire, although the basis for these claims is not clear.
